Alkanes are found in animal products, although they are less important than unsaturated hydrocarbons. One example is the shark liver oil, which is approximately 14% pristane (2,6,10,14-tetramethylpentadecane, C 19 H 40). They are important as pheromones, chemical messenger materials, on which insects depend for communication.

Higher alkanes are naturally present in crude oil and can be obtained via fractional distillation.Saturated fatty acids decarboxylate to higher alkanes. Long olefins can be hydrogenated to yield higher alkanes. n-alkanes can be isolated via the formation of urea clathrates.They can also be synthesized through Kolbe electrolysis or other coupling reactions like the Wurtz reaction.
Alkanes as substituents are called alkyl groups Subcategories. This category has the following 5 subcategories, out of 5 total. B. Butane (2 C, 11 P) E. Ethane (1 C ...
Hexadecane (also called cetane) is an alkane hydrocarbon with the chemical formula C 16 H 34. Hexadecane consists of a chain of 16 carbon atoms , with three hydrogen atoms bonded to the two end carbon atoms, and two hydrogens bonded to each of the 14 other carbon atoms.
Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
Some important classes of organic molecules are derivatives of alkanes, such as the primary alcohols, aldehydes, and (mono)carboxylic acids form analogous series to the alkanes. The corresponding homologous series of primary straight-chained alcohols comprises methanol (CH 4 O), ethanol (C 2 H 6 O), 1-propanol (C 3 H 8 O), 1-butanol , and so on.
The prefix consists of three numbers that are arranged in descending order, separated by dots: [2.2.1]. Before the numerical prefix is another prefix indicating the number of rings (e.g., "bicyclo+"). Thus, the name is bicyclo[2.2.1]heptane. Cycloalkanes as a group are also known as naphthenes, a term mainly used in the petroleum industry. [4]
